Consider the following hypotheses test.  Ho: m ³ 80   Ha: m   A sample of 121 provided a sample mean of 77.3. The population standard deviation is known to be 16.5.a. Compute the value of the test statistic. b. Determine the p-value; and at 93.7% confidence, test the above hypotheses. c. Using the critical value approach at 93.7% confidence, test the hypotheses.
